I know Skylar came on this thread a while ago to confirm that the Carbon was sonically the same as the original NH, but to my ears they sound a little different. (I have both. Three pairs in total actually). The Carbon is a touch less fulsome in the bass, a little more linear you might say, and a touch brighter up top. Not majorly, but noticeably, when directly A/B-ing them. I haven't formally measured them though-- I'm just a passionate listener. I'm not trying to reignite any controversy about it; I just believe this view should be known for anyone coming new to the NH. Perhaps it's down to individual model's idiosyncrasies, break-in time, etc., I don't know. But I hear a slight but real difference. Your mileage may vary.
